Big Blue - CF900 Magnetic Switch Problem

[Pedro Burrito]

I've owned a Big Blue CF900 for almost 2 years. It worked fine until recently. I turn it on now but the light is dim. I thought it was the battery so I switched it with another Big Blue rechargeable battery. The battery was fine but the light just isn't bright anymore.

Is there a way to adjust the magnetic switch? There is a ring above the rotary switch with two small Phillips head screws. I unloosened the screws and the ring slid up. The rotary part of the switch slid up too but the light output is still very dim.

Any ideas?

Thank you.

check magnetic switch with another powerful magnet ( bypass original magnet )

check led temperature ( might led loose thermal contact , then overheat , then driver might start thermal protection if it have )
